Breaking Point: How Long Can Someone Go Without Breathing? Humans are aerobic creatures, meaning we require oxygen to release energy and exist. Without oxygen, our cells wouldn’t be able to release the energy in the food we eat, and we would die. We take in oxygen through respiration — we move air in and out of the lungs, and blood takes oxygen to the cells of the body. Carbon dioxide, a waste product in our bodies, is moved out of the body by the same system.

A lack of oxygen from three to nine minutes can result in irreversible brain damage! In case of a cardiac arrest a CPR (Cardiopulmonary resuscitation) is best started within two minutes. An ischemic stroke occurs when a part of the brains die because of a blocked arteria which lead to a partial lack of oxygen:

What Happens After A Lack of Oxygen to the Brain? Between 30-180 seconds of oxygen deprivation, you may lose consciousness. At the one-minute mark, brain cells begin dying. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent. At 10 minutes, even if the brain remains alive, a coma and lasting brain damage are almost inevitable.

CG2 If your lungs are healthy, and you have no breathing difficulties, your body has all the oxygen it needs, says Boyer. In hospital settings, 100% oxygen may be delivered -- but even then only on a short-term basis, says Boyer -- less than 24 hours and preferably less than 12 hours. To breathe pure oxygen at that level for any longer can have toxic results, including shock lung, or adult respiratory distress syndrome.
